Hi Paul, you’re definitely on the right track here, and I can help you narrow this down with confidence. With your tandem 3,500 lb Dexter axles and 33 inch spacing, both the Dexter EZ Flex part #K71-652-00 and the Lippert Road Armor part #LC53CK are…
You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…
Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…
Hey Ian, great to hear from you again! The differences between the MORryde CRE3000 #MR87ZR and AllTrek 4000 #MR89DR that fit a 33" wheelbase is the height between the hanger and equalizer bolts, and the amount of travel the suspension style will…
I would love to help you upgrade the suspension on your Twilight 2800 travel trailer. The MORryde Rubber Equalizers for Tandem Axle Trailers #MR87ZR that you referenced are a great solution but we do need to double check a few things. First is that…
Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…
Hey, Lance. The direction the springs are in doesn't matter. They can be to the front or to the rear of the axle and will perform the same either way. What kind of trailer are you working on?
The determine the correct replacement leaf spring on your 2021 Coachmen 259FKDS you'll need to lift your trailer frame so the spring is hanging freely and then measure from center-eye to center-eye, then for the equalizer you need to measure…
Hello Lanny, thanks for reaching out. The CRE 3000 is already a pretty good suspension system, but if you want to upgrade, the first thing that comes to mind are the AllTrek 4000 equalizers. They have more rubber than the CRE 3000, 40% more, so you…
Hi Greg; I wish there was a way for me to know the correct parts for that 2023 Coachmen Catalina but we don't have a way to look it up. The only company that lists their parts like that is Grand Design. If they can get out to their trailer and…
The Lippert Equa-Flex #LC145546 is the closest cushioned equalizer from Lippert to fitting your Grand Design 2800BH. This particular kit is rated for 5K-8K axles. The MORryde CRE3000 #MR27ZR is going to be the best option for your camper. While this…
We have lift kits for trailer that easily add 2 inches to the height of the trailer. For that you'd want the part #RR23QX and you'd be set. I attached a picture that shows how it installs to give you an idea. This would be the easiest…

Trailer Suspension Parts with Leaf Spring Replacement System
Looking for a smoother, calmer tow? A leaf spring replacement system uses slipper springs for better control, and kits are available with shock absorbers. Match spring rating to your axle—use 7K with 7K axles; 8K can work on 3" tubes but rides more aggressive and may need new 3" tie plates or U-bolts. These systems don't include wet bolts, and with slipper springs only one wet bolt fits per leaf spring; check hanger areas for any plumbing first.
They generally do not include wet bolts, and slipper spring layouts use fewer greasable points. You can add wet bolts at the main spring eye to help keep water and rust out. Use a quality high-stress grease during assembly to maintain smooth movement.
Yes, they can noticeably smooth the ride and reduce bounce and fore/aft movement. That helps keep items inside from getting tossed around. Adding shocks with the springs further reduces vibrations and helps the trailer feel more planted.
Go with 7K springs for 7K axles for the best ride. Heavier 8K springs can work but may feel more aggressive and stiff. Match the spring rating to your axle rating to help smooth out road seams and reduce harsh feedback.
Confirm your axle tube diameter; common sizes are 3" and 3-1/2" and larger tubes may need adapters. Verify hanger space so shocks and brackets won't conflict with plumbing or other components. Check if your existing U-bolts are long enough; some setups need new tie plates and U-bolts to fit heavier hardware.
